Clicker concept vs. Clicker hardware

The first time I saw a demo with clickers, I was hooked. I was a doc student at the University of Virginia, and the Curry School of Education had a class set of  30 clickers and a receiver that professors could check out and use with their classes. A colleague and I checked out the clickers to use with a class of preservice teachers. We spent about two hours setting them up and testing them, and everything seemed to be on track for an exciting romp of student engagement and deep learning. (sarcasm). Honestly, we just wanted to see how they worked and look cool in front of the students. The short story is this activity totally flopped. The student accounts did not work and only about one-fourth of the clickers would register with the receiver. We spent a little time doing the awkward technology dance, then we bailed on the idea and proceeded with our activity sans clickers.

I have had this same experience in a dozen or so classes, workshops, meetings, and conference presentations. Thankfully, none of these have been at my expense, other than the annoying time lapse created by people insisting something will work if they bang on it long enough. In my own teaching, I had all but abandoned the use of clickers simply because they never seemed to work properly. Rather, I would use strategies that I knew were more stable, such as Google Forms. I could create a short form, send it to the students (via e-mail or a bit.ly address) and get instant feedback from my students. The interface was pretty simple, and assuming I didn't ask my students questions requiring a long, wordy response, I could take a quick pulse from the class in a matter of minutes.

Most of my classes have met in computer labs, so access to a browser has never been a problem. However, I had to rethink how to implement this strategy when I was in a traditional classroom. I tried having students send responses from these forms using their phones a couple of times, but the forms did not render very well on the small screen. This was also before smartphones had the kind of saturation they do now. About half my students had smartphones, and some of them were a little sensitive about using data for school activities (though no one seems to hesitate when it comes to sending and receiving texts during class). Go figure.

Once I started teaching a large lecture-type class at TCU, I knew I had to start thinking again about ways to engage the class. I found it very difficult to encourage discussion among a hundred students, and the "think, pair, share" technique was wearing thin because their mini-discussion never went anywhere. Very few of the students actually wanted to share their conversation with everyone else, and those that did were my usual suspects who did all the talking. I began researching ways to facilitate clickery-type activities in my large class without making the students buy actual clickers (at a $100 a pop) or bring their laptops (and all the wifi connectivity issues that come along with that).

After a lot of searching around and trying different apps, I settled on Socrative. Socrative is an app that works on multiple platforms (i.e., browser, iPhone and Android app, tablet), and it can be controlled by the teacher from either a computer or mobile device. Teachers can send out general questions (Multiple Choice, True/False, Short Answer), or they can create quizzes ahead of time and send those to students. Responses from preformed quizzes can be aggregated into a spreadsheet and sent to the teacher for later analysis. There is a separate app for teachers and students, and there are separate URLs for both if anyone is using a browser.

The best feature of this app, in my opinion, is the ability to create quizzes in a spreadsheet and upload them to the teacher account. I have found the spreadsheet to be much easier to use than the web interface because of how easy it is to copy and paste items, as well as move things around. Here is an example of a quiz created using the template, and you can download it from Socrative here. Once students have completed a preformed quiz, you are given the results in a spreadsheet. Below are two examples of what these reports look like. Correct answers are highlighted in green and incorrect in red. You can also see if a student did not respond. Students have to enter their name before they start the quiz, but I deleted them in these examples.

• Example 1
• Example 2

Running a close second to the spreadsheet-import feature is that results are updated in real time on the teacher app or account. I could display the teacher screen and see the results change as students sent in their responses. I still have not found a way to show both the questions and the results at the same time, but this hasn't been a deal breaker for me.

Quizzes can take the form of traditional MC or TF, short answer, Space Race or short answer. My college students had a strange euphoric response to the Space Race activities, which I cannot fully explain. Actually, the response from the students was very positive. They all added the app to their phones, and I would put SOCRATIVE at the top of the page that included a question. Without fail, when  SOCRATIVE popped up on the screen, the class instinctively grabbed their phones and waited for the question. They even memorized my room number, which was helpful for those times I became the absent-minded professor and couldn't remember it.

A final perk of this tool is that it runs through the Cloud rather than relying on infrared sensors to send and receive signals. As long as both the student and teacher devices are connected to the Internet, the tools works. To date, I have used this tool about 100 times and never had issues with data being received. I have had a few instances of students getting a weak signal on their phones, but those instances have been isolated and infrequent.

On my mid-semester questionnaire, several students mentioned this tool specifically and remarked that they liked seeing the results from these short discussion questions show up immediately on the screen. Turns out, students like seeing how their ideas or opinions compare with everyone else. They also like using their own phones or computers to do this without having to purchase an clicker. Pedagogically, I would typically have the students discuss the questions in pairs or groups of three and make them converge on an answer. I tried to make the responses such that students had to choose between all seemingly good options. I like to think the discussion was the best part of the activity and the technology just facilitated it.

So, how do you facilitate class discussion? Do you use clickers or apps to do this? What are you techniques?

Mission Control

I have always been one of those teachers who likes to show a lot of stuff on the screen. Before projectors, I displayed graphs, charts, images, and graphic organizers using a TV or overhead projector. I have always loved supporting what I have to say with visuals. So, it should come as no surprise that my computer, or any computer, is a necessary resource for my teaching.

I also like to switch back and forth between media. I am that guy who always has about 10 tabs open in a browser, and an addition 5 programs running on my computer. I switch between slides to documents to video to applications. I'm sure this drives my students crazy, but they get used to it. One thing I never got used to was being trapped behind my computer while I teach. I am definitely not one of these roam-the-room types, but I don't like to stand behind my computer and constantly have to look down at my screen. Since I utilize far more tools than just PPT, the little clicker thing never really worked for me. What I have always wanted is a miniature control panel that fits in one hand and allows me to switch seamlessly between apps and media, and even mark up that media for emphasis.

Well, during the Fall semester this capability literally fell at my doorstep when my department bought me an iPad. I had always wanted to use an iPad, but I didn't want to spend the money. I tend to be a late adopter when it comes to new devices. Anyway, I got the news from my dean that I would be getting an iPad, so I began researching ways to use it as a mission control for teaching.

Mirroring

My first task was to figure out how to mirror my iPad on the screen of my MacBook Pro. I discovered there are basically two ways to do this. You can use the iPad as a remote desktop and control the computer using the device. I tried PocketCloud, Doceri, and Splashtop 2. PocketCloud never really worked for me. I would be logged in, but I would have trouble connecting my two devices. Doceri worked pretty well, and even allowed me to mark up the screen, but it cost money and I didn't really like trying to find things on the screen. Besides, I was far more interested in teaching from the iPad apps than I was using the programs on my computer. Splashtop actually works really well, and I was able to get it for free. However, it is still just a remote view of my computer, which is not what I want. I much prefer the interface and ease of use of the iPad.

To keep this short, I settled on AirServer to mirror my iPad on my MacBook. There are a couple of programs that do this, and I liked this one best after downloading a couple of demos. AirServer fools your iPad into thinking your MacBook is an Apple TV, so you can use the built-in AirPlay to wirelessly mirror your device. For AirServer to work, your MacBook and iPad must be on the same wireless network. My university is very strict when it comes to using the wireless network, so this kind of thing is blocked. I found out, however, that I can pair my MacBook with my iPad using Bluetooth, and it works just the same. The only hiccup is when I try to stream video from the iPad to the MacBook via Bluetooth. It almost always freezes, so I have started playing video files directly from the hard drive. Other than that, this is a great solution that has not failed me yet.

Apps

The next thing I had to do -- and I am still doing -- is find apps that enable me to enhance my teaching with the iPad. I mean, if there is no value added, then why spend $12 for AirServer and bother figuring out how to mirror the display? I did quite a bit of reading and researching different apps that do the things I want to do in my classes, and I have found a pretty nice set that I rely on regularly. Here they are by category.

Presentation Slides

• SlideShark: Easy to import and sync from the cloud, and maintains animations and formatting
• Explain Everything: A nice combo of slides and an interactive whiteboard. Also lets me record my talk and upload it directly to Google Drive or YouTube (which I have yet to do.) By the way, when I Google "explain everything," it gives me a definition for the word "everything." Now that's pretty funny.

Cloud Syncing

• SugarSync: This lets me sync everything (that I want) from my computer to the cloud. I can then access it from the iPad and send it to just about any app.
• Google Drive: This basically does the same thing, with the added bonus of displaying Google Docs, which I use a lot. This interface is also much better for images and PDFs.

Student Engagement

• Socrative: This is a clicker app that still just blows my mind. I hope it stays free forever, but I'm sure it won't. I can send out quick polls to my class, both forced-response and open-ended. I can also create quizzes and exit tickets, and have the results e-mailed to me in a spreadsheet. I will probably write exclusively about this app later.

In order to demonstrate how this works, I have created a short video of how I move between apps during one of my class meetings. This is unedited, but you will get the point.

"I used to think I was good at explaining stuff ... "

I've taken a hiatus from this blog since August 28. I actually have started three other posts that I abandoned for various reasons. Well, now I'm back. For now.

This year as I began my new position, I was given access to a whole new variety of digital tools. At UNT, it was digital fabrication and energy monitoring. I had enough devices to give one per group of students, which meant I could do some really cool things. It's a lot of fun teaching project-based learning to future teachers when you have the tools to do it. Of course, there were other things we didn't have at UNT, like interactive whiteboards and mobile devices (specifically, iPads). So, there were some other important skills that were hard to teach.

At TCU, I don't have the project-based learning tools, but I do have an interactive whiteboard, my own iPad and cart of 20 iPads for students to use in class. This has opened up a whole new domain of learning and teaching with technology. I have been able to do activities with my classes I thought I would never be able to teach. My goal over the course of the next several weeks (months?) is to post some of these activities, along with examples from students.

The first activity I would like to talk about is Flipped Classroom lessons using Educreations. I have been piloting several of these Digital Whiteboard apps, such as Show Me, Explain Everything, and Knowmia, and Educreations was the best fit for this activity. Show Me also would have been a good fit for my activity because it instantly syncs lessons to the Cloud and you can access the video files from a browser. Additionally, it lets you download a copy of the video file to your computer in case you want to do additional editing or combine lessons. Educreations does not have this capability yet. As a side note, Explain Everything (paid) and Knowmia (free) are very robust tools and worth learning. They allow you to import and export media and projects to other Cloud services like DropBox, Google Drive, Evernote, and Box. There are many tools for presenting content, including embedding web pages, video, and audio files.

For this activity, I gave the students three "badges" they were to earn: video editing, screencasting and a flipped lesson. The idea behind the flipped lesson is that students present content to students to watch and learn at home with the intention of doing more collaborative, hands-on activities at school when everyone is in the same room. The students worked in pairs to create and record a short lesson, which they later uploaded to the class Educreations account.

Beyond the simple interface of the tool and how fun it was to create mini-lessons, I knew this was the only way for my students to see the importance of developing this competency as a future teacher. The students commented on how great it would be to create examples for how to correctly work math problems, edit their writing, convey science and social studies concepts that students and parents could watch at home during homework time. This is usually when students have questions, and many parents feel frustrated trying to help their children. I can't speak for everyone, but I routinely would tell my dad, "But that's not how the TEACHER did it!"

An added benefit for this activity is that students got to practice explaining academic concepts at a level their students could understand. You really have to think about such aspects as pacing, language, examples and sequence when you are planning these lessons. The students were able to practice presenting to students without dealing with some of the environmental factors that often stump early-career teachers, such as crowd control and limited attention spans. As one student explained, "I used to think I was good at explaining stuff, but this activity really forced me to think about what I was saying and how fast I talk." Even though this was not my intention, the class got an impromptu lesson on micro-teaching.

I plan on integrating this strategy into my classes many more times in the coming semester. Ideally, I could work with a teacher (or two or three) and have my students create mini-lessons based on the content being address in the schools. My students would get experience teaching lessons in a concise, understandable way, and the teachers and students would have resources to utilize at home. An added benefit would be feedback from teachers and students about the quality of their lessons and explanations. We'll see how this goes.

To see some examples created by students in my class, visit our Educreations page.

Connected to what?

I've had this thought more than once during the past few weeks: What if I delete my Facebook account? I have no real reason to delete it, and I certainly have nothing against Zuckerberg or the company (though recent history has definitely exposed his true business sense). I haven't posted anything I'm trying to hide, and there is no one in my Friend list who I believe to be a liability. So, what is the source of these feelings?

Hollowness.

That is the feeling I am left with when I look at Facebook. To me, it is a very hollow. I know it is not that way for everyone, such as my sister who is very involved in playing various games with several of her friends. I know many people who chit-chat back and forth with their friends all day, as if they were in the same room. I think this is great, but it's not the experience I have had. I'm not sure it's the experience I want to have.

The obvious advantages to Facebook are the networking and being able to see what people are up to (assuming they choose to share their lives) without having to ask. Networking, especially in this day and age, is a benefit. It's nice to have a central place where you can send people messages, knowing it will go directly into the e-mail inbox. It's also frustrating when you never get a response from someone, knowing your message went directly into their e-mail inbox. To this end, I would say this has been my main use of Facebook.

Facebook also does a nice job of keeping people who would not ordinarily be in your consciousness in your consciousness. Stalking, lurking or whatever you want to call it probably is not a benefit, except for those moments when you think, "I wonder whatever happened to old So-and-so," then you proceed to find him or her on Facebook, only to discover he lives in Peoria, Illinois and sells sand to hourglass companies. "Oh," you think to yourself, and move on. But at least old So-and-so is in your thoughts in some way, which is a way to stay connected to your past, I guess.

For me, the hollowness comes from knowing there are many people in my Friends list who want to know about me but aren't really interested in knowing me anymore. They want to have a connection to me in case I ever come in handy but they aren't committed enough to actually connect. I have a handful of friends who actually do write back, chit-chat or want to get together from time to time, but I am starting to think those are the friends I would have stayed in touch with even if there were no Facebook.

Like I said, hollow.

The main question for me, however, is not the impact this 21st century digitally-driven social networking has on me. I'm a grown-up with a great job, wonderful family and sense of purpose in life. I can deal with a little hollowness. The bigger question is how does this type of connecting affect people who have never known anything else? How are my children going to define friendship? Will they grow up thinking that people are information you need to simply find out? That once you know the person's information, you "know" that person? Will they believe the lie that you are what you share? Will they feel compelled to tweet, update, instragram or whatever every single experience they've had, or even worse, manufacture experiences just because they think they'll make for a good tweet, instragram or update?

When I think about the true friends in my life, I think of inside jokes, mountain adventures, long stories to fill long bus rides to school events, secret pacts made by a campfire, calling each other over college breaks to find time to hang out. I think about talking over dinner, serving together with someone other than ourselves in mind, playing phone tag for weeks until one of us catches the other person at home, road trips. Friendships should be so heavy with shared experiences they leave a wake in our past that never really dissipates.

I'm sure my children will use Facebook (or something like it), but I am starting to believe I will have to be purposeful if I hope to keep it from becoming the central piece in their social lives. Lives are more than data, and connection is more than updates. One way to help with this is to keep my account open and use it responsibly. And Friend them when they're old enough.

Guest Blogging in the U.S.A.

The following post is something I wrote as a guest blogger on Wes Fryer's popular blog, Moving at the Speed of Creativity. My contribution will be posted on June 21.

The satisfaction to be derived from success in a great constructive enterprise is one of the most massive that life has to offer.

-Bertrand Russell

The first time I remember “creating” something for a school assignment was in 3rd grade. Up until this point, what I remember about school involved completing worksheets at my desk, reading from various texts in front of the whole class, and being placed in groups based on my ability in math and reading. This all changed in Mr. Beaver’s class, my 3rd grade teacher.

Mr. Beaver involved his students in various activities and challenges, most of which required us to build something with materials we found at home. He would come into class one day and toss out some ambiguous statement as if it were a hook with a worm: “My daughter bought a kite this weekend, and it works pretty well. I wonder if she could have built a kite out of supplies she found at home. Nah, probably not. That’s too hard for someone her age.” This was just enough for a few of us to go home and try to prove him wrong. During the school year, we had several projects that involved creating things: electromagnets, dioramas, kites, maps. For a kid who liked making stuff anyway, it was a fun year in school.

This experience probably planted the seed in my mind that projects are a fun and engaging way to learn. As a teacher, I tried to implement several different projects throughout the year, and now I spend a fair amount of time helping other teachers design and implement student projects in their classrooms.

Most of the work I have done in recent years has centered around digital media: teachers helping students combine images, audio, video and/or text to express their learning through such products as digital stories, documentaries, podcasts, virtual museums and comics. More recently, however, I have been involved in projects that cross over from digital media to physical media, otherwise known as digital fabrication or desktop engineering.

The focus of this initiative, under the direction of Glen Bull at the University of Virginia, is to teach students to apply math, science, engineering and technology skills and concepts to real-world problems. Students create digital models of objects such as electrical circuits, windmills, and gears, print and cut them using special equipment, then construct the components into a physical object. This short video describes the process of digital fabrication.

The concept of creating virtual 3D representations of objects before creating the physical object is not new. Many of the things we use everyday - cars, homes, buildings, city plans, electronics, and aircraft - were first designed and tested in a virtual environment before the physical object was ever built. Similar to storyboarding in movies and game design, virtual models help designers test and troubleshoot their products without making potentially costly mistakes that waste resources. As teachers, we want our students to be problem solvers and identify areas for improvement early in a process rather than later.

An integral part of this initiative has been training teachers - both in-service and preservice - how to integrate engineering and fabrication activities into their existing curriculum. Our research has confirmed a line of previous studies that many in-service and preservice teachers, especially at the elementary level, lack confidence when it comes to teaching math and science. This can be a barrier when it comes to encouraging teachers to create engineering design projects for their students. In response to this problem, we have been replicating engineering design projects being done with 4-5 grade students in Virginia with preservice teachers in North Texas.

If you are interested in reading examples about digital fabrication in a teacher education course, I have provided a few for you here:

• Teaching Virtual Design in a Physical World
• Implementing Digital Fabrication
• Digital Fabrication, take two

The University of Virginia also has a wealth of resources on this topic, which can be accessed for free on the Make to Learn website. Most of these activities do not require a Silhouette cutting machine and have been successfully implemented in some classrooms with nothing more than scissors. I have also found some excellent activities at robives.com, but I have yet to try any of them with students or teachers.

My hope is that sharing some of the work being done in the area of desktop engineering with a larger audience will generate some interest in doing this type of work in the classroom. This initiative is in its infancy, yet it has already attracted quite a bit of attention and buy-in from several school districts, universities and the National Science Foundation. The need for our students to be creators, thinkers and innovators has never been greater, and there seems to be no better way to foster these qualities than to engage students in activities that require creativity, thinking and innovation. Students already have a reputation for being massive consumers of digital media and other technological innovations, and they are one of the largest groups to create and share digital content. Now, with the emergence of desktop engineering we have the resources at our fingertips to help them discover the relationship between virtual and physical media and further explore what it means to play with media.

Why digital text is here stay

As if anyone would even argue this point, I just had a flash that served as one more reminder why digital text is here to stay. This is also why The Cloud is here to stay, and why eReaders are here to stay, and why the discipline of close reading is here to stay. Here's what happened.

I was crafting an e-mail to a friend about a possible digital media study this upcoming fall. In my message, I decided to mention Jonah Lehrer's book ... again. Have I told you about his book, Imagine, lately? Do you need the hyperlink so you can buy it? Am I a sycophant yet? Anyway, there was a phrase from his book that I wanted to use (i.e., claim as my own), but I couldn't remember it. I reached to get my Kindle, and realized it was at home, as are all of my other devices that have this book on it. So, I looked up Kindle on Google, and found out they have a Cloud Reader for computers. Why wouldn't they? I mean, Amazon can sync my other devices so that when I put one down and pick up another later on, I start reading right where I left off. In a matter of 5 or so clicks, I was looking at Lehrer's book at the exact place where I stopped reading last night. I located the phrase (meta-idea), and went right back to my e-mail. Actually, I came right to my blog, then I will get back to my e-mail ... after lunch.

This kind of thing was not even possible a few years ago. If I needed to look at something in a book, I had to either bring the book with me or wait until I got home, to my office, etc. Now I have every book I own (in digital format) right in front of me whenever I need to look something up. I don't think I will ever buy another printed book again. I'm sure publishers will still send me copies of books to review, but if they ever give me the option, I want the eBook. It's important to note, I still had to read the eBook. If I want to make a note, I have to actually make the note. If something in one book makes me think of something in another book, I have to be disciplined enough to write it down before I forget. The eBook (or any digital media, for that matter) does not do the thinking for you, but boy oh boy, does it change the way I approach my scholarship. I love the Web because I find all kinds of resources I never knew existed, but what I really love is to be able to reference those resources I have already read, thought about, re-read, took notes on, and integrated into my existing knowledge base. The perfect storm of taking the time to sit still and read something, mixed with ubiquitous access when I can't remember a phrase or term or quotation. It's the epitome of distributed cognition, to me.

Oh, and my back doesn't hurt anymore from lugging around all those books.

Podcasting and Learning

I've been orbiting and occupying this big ol' Ed Techy world for quite a long time. So, I've read countless papers, proposals, articles, and chapters on "Why my media is better for learning than your media." I've studied this from a cognitive, social, motivational, and developmental perspective, and I am still not convinced that one medium is better for learning than any other. I do believe that all media have different affordances that make them better-suited for certain contexts, learning styles or learning tasks. Needless to say, I've done (and continue to do) my homework  on this one, and I get a little annoyed when people who just perhaps haven't done as much homework on this topic make blanket statements like this one:

 A new study found that students who listen to lectures on podcasts test better than those who listen in class. (You can read the entire article here.)

The "new study" in question is taken from a 2009 article in New Scientist, and it's reporting on a study done in the same year by Dani McKinney. I found these links in a 2012 blog post by Michael Hyatt. My issue is not with bloggers quoting bloggers quoting bloggers, some of whom don't understand educational technology research. The problem I have with this quote, and those like it, is that it is stated as if this were "proven" fact. Here are some things to consider when reading results from this type of research:

1. Learning is complex and influenced by many, many factors: motivation, engagement, prior knowledge, environment, aptitude AND delivery method. To say that students who listen to a podcast at home will score better on a test than those who come to class and listen to the lecture is absurd. This can lead to all kinds of misconceptions about learning, multi-tasking, learning styles and media. "You can learn astrophysics while washing the dishes and updating your Facebook status!"
2. Most educational technology research studies have a long list of limitations. The findings are almost always limited to the study in question, with some suggestions on how to scale it up or replicate the results. This is called "job security" for us academic types.
3. Teacher-created exams may not be the best measure for student learning. Sure, they're great for assigning grades, but they are often mismatched with the learning objectives, and if they are multiple choice, there's a chance the students could guess and get the right answer. The test items may also be written in such a way that it is easy to eliminate answer choices and choose the right one without really knowing the material. I did not read the entire research article, so I will not make any judgments about this instructor's exam.

Online and hybrid learning environments are here to stay, and the research into best practices and learning outcomes for this model of teaching will only get broader and better. Studies such as the one I reference above are an important part in this process and must be done. Any research study should produce more questions than answers, which this one obviously did (Do podcast lectures have the same effect over an entire semester?) But please, if you are going to quote studies like this, look at the original research article and temper your statements with a qualifier or two. Michael Hyatt and Mile Elgan have thousands and thousands of readers. If I go back and read this tonight, I will have one. People believe what they read, and they especially believe what they read when they WANT to believe it. If you want to do better on tests, or learn something new, try the time-tested strategy of applying yourself and taking ownership of your learning. Don't expect media, podcasts or otherwise, to do for you what you aren't willing to do for yourself.

Wikispaces: One-stop shopping for digital learning

In the past several years, I have come to rely on Web-based website builders quite extensively in my teaching. I typically use Google Sites for the bulk of my Web content with my classes, and it has always been very reliable. I have noticed lately that the editor doesn't always load in the newest versions of Firefox. This isn't a big deal because I can jump over to Safari and finish whatever edits I need to do.

Anyway, what started as a way to write lesson plans without having to move files with me wherever I went has evolved into a complete lecture management tool. I started using SeedWiki circa. 2005 because I found myself planning my lectures at odd times, using a host of different computers. Using a wiki was a perfect solution because I could log in from anywhere and pick up where I had left off. I also liked the wiki because I could paste links and other resources directly into the page. It was a great tool.

Eventually, I started giving my class the link to my lecture notes in SeedWiki, and it wasn't long before I was using the wiki as the hub to my class meetings. I got this idea, in part, from someone else, and though I have switched tools I still use this method for managing class meetings. Some of the basics methods that I use a wiki for include:

• Time management: I would organize each section of the class meeting using cells in a table, including the amount of time I thought we would spend on each section. Each section of the class meeting has relevant links, embedded videos, documents, etc.
• Collaborative Learning: Keeping track of group work and collaborative learning can be a nightmare. One area of my teaching that I noticed was in serious need of improvement was keeping the class on track during group discussions. We've all seen this technique used, and it did not come naturally to me. What I noticed in many instances was that the students would spend about 60 seconds discussing the topic, then they would digress into conversation and have nothing to show for their work. Essentially, group discussions lacked accountability and there was no incentive for staying on task. What I began to do, and do to this day, is determine ahead of time how many groups the class would be divided into and create that many pages as part of the class wiki. Each group would then summarize their discussion on the assigned page. I was able to get creative too, throwing in such tasks as finding a random picture on the web, or finding a movie clip that corresponded to their main idea. As soon as the group clicked save, I was able to display their summary to the rest of the class. I had a built-in record of what each group talked about, and because anyone could edit the page, no sign-in was required.
• Lecture Archive: Because everything that we covered, as well as what we did in class, was saved to the wiki for that day, I had a detailed archive of the class meeting. More detailed than I could have created on my own because the class helped me do it. So, when a student would come to class and ask that question that all professors love to hear ("Did we cover anything important last week?"), I could point them to the wiki and tell them that EVERYTHING on the page for that day is important.

About the time that SeedWiki went under, Google Sites (which used to be JotSpot) came around. I was already a big Gmail and Google Docs user at this point, so it made sense to start using Google Sites to manage my lecture notes. The tool itself is very stable and easy to use, but it was not ideal for collaborative learning. Students had to have Google Account and be added one-by-one to the Site before they could log in and participate in the learning activities. This may not sound like a big deal, but there were just enough moving parts that it became a nuisance. Remember, college students are basically high school students with no curfew and more access to beer, and many of them are not good at keeping track of their information. Just to give my students permission to co-edit the class Site, they had to:

1. Open a Google Account
2. Send me the e-mail address they used to open the Google Account
3. Respond to my invitation to join the class Google Site
4. Remember their log in information

When you go to start a class activity and half the class can't access the Site, it gets pretty frustrating. UVa eventually moved to Google Apps for student e-mail accounts, so this reduced some of the friction, but it was still very clunky. In Google Sites' defense, I don't think they ever intended for the tool to be used in this way, and restricting editing access to only those with permission is a security measure.

Recently, I rediscovered Wikispaces, and I think the tool has come along to point where I will start using it exclusively for all of my lecture management needs. I typically use Wikispaces about twice per semester with each of my classes, but I am starting to see how it is much more effective than Google Sites for use in a learning environment. First of all, the teacher can add users to a wiki in bulk. All you do is create  a spreadsheet with usernames and passwords, and upload it to the wiki. Students then have access to the wiki, and they didn't have to sign up or respond to a confirmation e-mail. This option is superior to making the wiki editable by anyone, as you will see later.

Second, you can create Projects within the wiki. These projects are partitioned off from the rest of wiki, making it much easier to manage each activity. Otherwise, the list of your wiki's pages gets to be pretty burdensome and hard to manage. Every time you create a new project, you can drag-n-drop the names of students into different teams, or you can let Wikispaces randomly assign students to teams. This is great for mixing up student groupings and getting students out of their comfort zones. The alternative is letting the students always pick their own groups and essentially work with the same people all semester.

Finally, there is a Discussion tab for each page, which you can use in several different ways. You can have students follow up with group projects by discussing key questions in a back channel. I haven't used this particular feature much, but I plan on using it more.

There are many reasons to use a wiki to manage your class meetings, some of which I have discussed here. What are some other ways you have used a wiki as part of your teaching?

Saving the world one student at a time

When I arrived at UNT, one of the projects already underway in the research center where I work was MSOSW (Middle Schoolers Out to Save the World). The focus of this project is to increase middle school students' interest in science, technology, engineering and math through a problem-based unit focused on energy conservation. The students participating in this project, which included schools from Texas, Louisiana, Maine and Vermont, use Watts Up? devices to measure the amount of vampire energy used by the electronic devices in their homes. This project involves a lot of in-depth learning about energy consumption, carbon emissions, measurement units for energy and power, energy costs, carbon footprint, stand-by power and product design. In addition to these concepts, the students are required to do a lot of math for conversions, and they must use a spreadsheet. Because I see such value in these types of projects, I wanted my pre-service teachers to experience firsthand what it looks like to complete a problem-based unit from beginning to end. I observed this unit being taught last year at Good Shepherd Episcopal School, but I had never actually planned and taught it myself. Let me tell you, the planning was much more time intensive than I had assumed, and I ended up staying up late one night to get all of the materials ready.

The first thing I did was put my students into groups of 2. I normally let them pick their own partners, but they have gotten, how shall we say, comfortable this semester, and I wanted to break them out of their apathetic little comfort zone. The next thing I did was set up a Google Presentation for each group. I wanted them to see how this tool worked, so I created one for each group and set them up so anyone could edit. The next thing I did was lay out the project on Glogster. I was never really happy with how this turned out, but you can see it here. The process of setting up this glog (their term, not mine) required me to go find all of the resources I wanted them to have for the project. This included a carbon footprint calculator, a vampire energy calculator, a graph maker, a couple of videos and a spreadsheet for entering some data. As the pre-service teachers went through this project, I had them report their information in the Google Presentation along the way. I also brought a few Watts Up? devices to the lab and hooked them up to a monitor, a CPU tower, the printer and the document projector. I wanted them to do the math required to calculate how much energy the lab uses in a 24 hour period. Overall, they did a really nice job and completed the whole activity, even though it was not for a grade (I will grade it in the future, I think).

Here are a few lessons learned from this tech-rich problem-based unit:

1. Pre-service teachers actually like this kind of work. I have to say, this was hard and the students really struggled with some of the math and science concepts. But they stuck with it and took the topic seriously. I would even go so far as to say they learned something about energy conservation from doing this. I also hope they learned something about using this teaching strategy with students
2. Glogster is kind of cool, but it has been extremely unstable and unreliable lately. On several occasions I have logged on and gotten some sort of "We will be down for the next 36 hours, but we are adding some really awesome new features!" Well, when I go to retrieve my work from a Web tool and it is not there, I'm done with that tool. That is a total deal breaker for me. So, Glogster, I am sure your new design is really awesome, but you let me down on several occasions and I'm done. I will also not be pointing my students to this tool because it let many of them down too.
3. When you set up a Google Presentation to be edited by anyone with the link, it will not let you import images. The students made a graph that was exported as a JPEG, and I wanted them to import it into a slide. Google Presentation wouldn't let them do it, so we found a very bothersome work-around. If we pasted the image in a PPT slide, we could copy and paste the graph into the Google Presentation (but only if we use CTRL-V, not the mouse). I don't know if this was a bug in the new re-design of Google Presentation, or if they have this feature disabled for when anonymous users are editing a document. Either way, it was annoying and slowed the process down temporarily. In a K-12 classroom, this could mean the difference between a project going well and the whole thing crumbling in your hands. I do have to own this one, though, because I never tried to edit a presentation or insert an image as an anonymous user. I should have done this beforehand, but I just took for granted that it would work.
4. Google Spreadsheet worked like a champ, and I will definitely use it in the future for activities like this. I have used this tool for years, but I had never seen multiple people entering in data at once. The students also thought this was really cool.
5. The Vampire Energy Calculator is very cool, and I think this is what really brought the project home for the students. Even the act of physically dragging electronics into different rooms made this more like a simulation than a calculator. It's a very well-designed tool.

So, that is my first attempt at teaching the MSOSW unit, but it will not be my last. I already have some ideas for how to make it better next time, and I hope this is serves as a catalyst for some students to begin envisioning this type of instruction in their own classrooms.

Digital Fabrication, take two

Yesterday I was asked to cover a class for one of my colleagues, so I planned another round of digital fabrication activities for his students. I had done the same thing last week with another colleague's class, using the materials I developed last year. The first attempt last week did not go nearly as well as I remembered the activities going last year, so I was motivated to rethink how I was presenting the content, as well as the activity I was having them do. The "old" activity was challenge that involved designing a container for tootsie rolls that would maximize the surface area:volume ratio. The concept was good, and the students approached it with enthusiasm. However, it turns out that their math abilities were a pretty major roadblock to getting anything substantive out of the activity. After the box was built and they stuffed it with tootsie rolls, the learning was basically over. This issue has roots in several factors that are true of most preservice teachers.

1. Preservice teachers' pedagogical knowledge has more to do with their worldview than their aptitude or attitude. Since most of them were taught from a traditional approach, the chasm between problem-based design activities and the lecture-test-essay model they are used to is a quantum leap. The problem is not that they are resistant to new pedagogical approaches; they simply have very little, if anything, to which to anchor them.
2. Before preservice teachers can understand something as a teacher, they need to take a step back and experience it as a student. Activities, therefore, need to be authentic and replicate, as much as possible, the way it might be done in a classroom.
3. Based on the previous two observations, if the instructor wants preservice teachers to abstract pedagogical principles from an authentic activity, he or she is going to have to lead them there. You can't expect inexperienced teachers coming from a traditional paradigm to naturally make connections between the activity they just did and broader educational ideas. It's like giving someone from a remote tribe in the Amazon rainforest a debit card and expecting him to naturally gravitate to an ATM and get some cash. The notion that there is "money" in a "bank" that can be "accessed" remotely just does not mesh with the way he thinks the world works.
4. Finally, authentic activities must be accessible. That is, they can not be too hard nor too easy. If the activity is too easy, the preservice teachers think it is fluff and busy work; if it's too hard, they can't envision themselves teaching that way. Either extreme will likely reinforce the worldview you are trying to change.

To improve on the previous activity, with these observations in mind, I designed the following challenge:

1. I started by describing the mentality of many students today, which is that every task they are given in school has a right answer, and their goal as students is to get the right answer the first time. Many teachers reinforce this mentality by how they conduct their classes. At present, the world works much differently than classrooms do. In the world, we encounter problems to which we must develop solutions. These problems are typically ...
• Ill-defined: the cause of the problem may not be readily apparent
• Ill-structured: because we don't know the cause, we don't know where to start exploring solutions
• Complex: there are many factors involved, each of which influences the other, and we don't know how changing one factor influences the other factors
2. I then tell them the story of William, a 14-year old boy from Malawi who had to drop out of school because is family was literally starving to death. They could no longer pay for his education, so he used the library to try to educate himself. From reading physics and "green" energy books, he got the idea of improving his family's way of life by building a windmill and generating electricity for his home. Using the images and diagrams from a book on wind energy (he was not able to read English very well at the time), he built his own windmill from old car, tractor and bicycle parts and provided electricity for his home. Soon, people from all over came to his house to charge their cell phones. Not long after this, he built another windmill to pump water to irrigate his family's crops.
3. I transition to the next point by telling the students that William solved his problem by using the resources available to him to create a solution to his problem. This took several attempts, and you can see how he improved his design from the first windmill to the second. In the same way, teachers need to provide opportunities for their students to solve problems using their available resources. Since there is no single right answer, students must be evaluated using different criteria.
4. I then talked about a new set of resources that students have access to. We talk for a minute about how everything they use now was first designed in a virtual 3D environment before it became a physical object we can use. I took a minute to show them ModelMaker, a simple tool for creating 3D shapes from 2D cut-outs.
5. I then explained the challenge, which was create a windmill that was able to lift a bucket of tootsie rolls. They would construct their windmill using card stock, a pencil and masking tape, and they would design their bucket using ModelMaker. The group able to lift the most tootsie rolls would win the  challenge, the prize for which was getting to eat as many tootsie rolls as they wanted. :-)

Here are some pictures of the activity ...

[/kml_flashembed]

In summary, this activity was a vast improvement over the previous activity. The preservice teachers were able to see for themselves how their design choices affected the way their windmill functioned. Some groups created a "cute" windmill that would not spin, while others created an aesthetically bland windmill that performed wonderfully. Some groups put more focus on the size of their container than they did on the design of their windmill, and one group created a wonderful windmill but their bucket too small. Had the bucket been bigger, they were convinced it could have carried the most tootsie rolls. For some of them, the fact that they created a machine that actually worked was very rewarding in itself. I will do some follow up with my own students to document their reactions, but my impression was that this was effective and worthwhile. And in the spirit of engineering and the design process, there was room for improvement.
